Non-Latin based languages, like Chinese, and also emojis use a different encoding process called Unicode or Unicode Transformation Format (UTF-8). It is meant to encompass all characters for efficiency but has a caveat. Each unicode character is 16 bits in size, which takes more information to send, therefore limiting SMS messages to 70 characters. Messages that are larger than 70 characters are also concatenated. These messages can fit 67 characters, and can be concatenated up to 4 times for a maximum of 268 characters.

Mobile advertising has become more and more popular. However, some mobile advertising is sent without a required permission from the consumer causing privacy violations. It should be understood that irrespective of how well advertising messages are designed and how many additional possibilities they provide, if consumers do not have confidence that their privacy will be protected, this will hinder their widespread deployment.[40] But if the messages originate from a source where the user is enrolled in a relationship/loyalty program, privacy is not considered violated and even interruptions can generate goodwill.[41]

There will be numbers for which an RVM cannot be successfully delivered on the first day you dial it. We will set the system to keep trying those numbers. This does not cost you anything, because you only pay for successfully delivered RVMs.
Similar to email, SMS has anti-spam laws which differ from country to country. As a general rule, it’s important to obtain the recipient’s permission before sending any text message, especially an SMS marketing type of message.
